title: A systematic review of the diagnostic role of ultrasonography in maxillofacial fractures.
abstract: This systematic review assessed the diagnostic value of ultrasonography in maxillofacial fractures. A computerized literature search of MEDLINE, PubMed and GoogleMed databases was conducted for publications on diagnostic ultrasound and maxillofacial fractures in English. Search phrases were 'maxillofacial fractures' or 'midfacial fractures' or 'zygomatic complex fractures' or 'nasal bone fractures' or 'orbital fractures' or 'mandibular fractures' combined with 'ultrasound' or 'ultrasonography'. The Boolean operator 'AND' was used to narrow the searches. 17 articles published between 1992 and 2009 were reviewed: two on midfacial fractures, nine on orbital fractures, three on nasal fractures, and two on mandibular fractures. One article described case series of ultrasonographic diagnosis of mandibular and midfacial fractures. The sensitivity and specificity of ultrasound in detecting orbital fractures were 56-100% and 85-100%, respectively, whilst that of nasal fractures were 90-100% and 98-100%, respectively. Sensitivity and specificity of ultrasonography in detecting zygomatic fractures were >90%. For mandibular fractures, the sensitivity and specificity was 66-100% and 52-100%, respectively. Much evidence justifies the use of diagnostic ultrasonography in maxillofacial fractures, especially fractures involving the nasal bone, orbital walls, anterior maxillary wall and zygomatic complex. The sensitivity and specificity of ultrasonography is generally comparable with CT.
